Figure 2-17 TL-2/F Fiber-optic Lobe Access Modules
The optical output power for the TL-2/F is:
•
-22 dBm into 50/125 fiber
•
-18 dBm into 62.5/125 fiber
•
-14 dBm into 100/140 fiber.
The receiver sensitivity for the TL-2/F is a minimum -32 dBm, with a
dynamic range of a minimum 20 dB.
The optical power budgets for three grades of fiber are:
•
10 dB for 50/125 fiber
•
14 dB for 62.5/125 fiber
•
18 dB for 100/140 fiber.
Note
When using a TL-2/F modules in a network, it is recommended to place a TJA
module for every 30-40 fiber connected stations, in each ring segment, if
there are no repeaters.
